The B.F. Goodrich Company developed this helmet from the Mark IV full pressure suit for the US Navy in the 1950s. The U.S. Air Force also authorized production of the Mark IV for squadrons stationed in colder areas. It was tested to altitudes of 139,000 ft. and demonstrated its ability to overcome the problems associated with safety during emergency ejection, immobility and manual pressurization. The helmet moved with the head via restraints, which allowed up/down mobility for improved visibility. It was a very successful design, and was modified later to become the spacesuit worn by the Mercury astronauts.
NASA transferred this helmet with other early human spaceflight test articles to the museum.
